About our remedial sealant in Westwood
A movement joint stops working when its sealant splits or sets hard. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have caulk or the wrong sealant used in a wet area and sealant applied over old sealant that has lifted, we can put it right, on leaking tray & enclosure joints, mouldy bath & shower sealant and expansion joints alike.
In a village or hamlet like Westwood, homes are often older cottages and farmhouses alongside a few newer houses. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Every job comes with a 12-month guarantee.

Advice
Westwood homes and their sealant
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
If you look after a building such as Bean Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s. For landlords with property near Longfield station, botched sealant from a previous quick fix is easier to strip out between tenants.
Westwood is about 3 miles south of Swanscombe, in Kent. Our applicators cover remedial sealant for householders, landlords and businesses in Westwood. 922 places in Kent are on our list, large and small. We also work in London, around 18 miles away.
We cover every part of DA13 and DA2 for remedial sealant. That includes homes and businesses on Westwood Road and Highcross Road. Close by, we work in Grubb Street (1 mile south-west), Green Street Green (1 mile west), Bean (1 mile north-west), St Margarets (2 miles west) and Darenth (2 miles west).

Local landmarks in Westwood
Locally, jobs take us to homes and businesses close to Longfield Academy, Longfield Chalk Bank and Railway Tavern, among other places.

For a walk, there’s Sawyers Lake.
What the job involves on each surface
Mouldy bath & shower sealant
Black mould inside the bead will not scrub out. All of it comes out, and the joint is treated and dried ahead of a new anti-fungal bead.
Windows & doors
Some leaks around windows come from the wall or the window itself. We check the joint and tell you if it looks to be something else.
What we cannot put right
It helps to know what we can’t do too:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- Failed tanking or loose tiles behind the sealant
- A bath, tray or worktop that moves until it’s properly fixed
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly.
What we seal
- Shrunken worktop sealant
- Failed movement joints
- Leaking tray & enclosure joints
- Mouldy bath & shower sealant
- Expansion joints
- Botched or over-sealed joints
When to call us in Westwood
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, and the sealant lifts or goes mouldy from underneath.
Common reasons people contact us include:
- Wide, uneven beads that look worse than the old ones
- Sealant applied over old sealant that has lifted
- Products that weren’t meant for the joint
- Leaks that keep coming back after resealing
In the older streets around Church of Saint Mary Magdalene, walls and floors in older homes can move, and sealant and grout show it first.
What to look for in a quote
- The length of the guarantee
- Whether VAT is included
- How long to leave it before use
- How the joint is cleaned and prepared
How we quote for remedial sealant
We do not publish a price list. The quote depends on:
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether the work is at height
- Whether there’s mould to deal with
Leaving a failed joint generally makes the job bigger, not smaller. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- The rough size of the job
- Where the property is
- Access, such as stairs, a lift or height
- The type of property
There’s no standard price list, as no two jobs are quite the same. Instead, we give you a clear price for your job. To get started, phone 0345 464 0079 or email us.
Why deal with it now?
Mould under a bead can’t be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. Older cottages and farmhouses around Westwood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
